Ischemia-reperfusion injury is universal in organ transplantation and leads to varying degrees of graft dysfunction. Despite this fact, the preservation method in organ transplantation has been left unchanged for many years and remains simple static cold storage. Given the scarce donor supply, an increasing number of so called marginal or extended criteria donor organs have been used for liver transplantation, grafts which were previously rarely considered. In addition, allocation policy has changed in many countries, and livers are currently often distributed by the severity of the recipient's disease. As a result, transplant candidates present sicker, with higher MELD (Model for end stage liver disease) scores, at the time of transplant,and the risk of graft dysfunction or even failure due to reperfusion injury is high after the use of marginal livers in sick recipients.
